Hi all I picked up this broken specimen out at Julia Creek (Western Queensland Australia) a short while back and assume it is a small shark Vertebra but would like conformation as it is worn.
The formation is cretaceous around 100 million in age - I still have to confirm the formation as I have never fossicked in the spot before as it was a short stop for lunch on a full day drive.
The specimen if whole would have been about 22 mm in diameter so is small. There appears to be quite a few growth rings so this may have been a quite small mature shark ? (Bramble)
